Digital banking platforms move money, store sensitive financial data, and answer to regulators all at once, which places them under a level of scrutiny that few other technology sectors face. Because of this heightened exposure, finding qualified SOC 2 auditors for digital banking platforms has become a critical step for any neobank, embedded-finance provider, or banking-as-a-service company that wants to earn institutional trust and close enterprise partnerships. Unlike a self-assessed security checklist, a SOC 2 report issued by an independent, AICPA-licensed CPA firm gives banking partners and regulators verifiable proof that a platform’s controls hold up under real, sustained observation.
Selecting the right auditor, however, is not as simple as picking a familiar name. Some firms specialize in cloud-native, API-driven banking architectures, while others bring the scale and regulatory relationships of a Big Four practice. Moreover, digital banks must weigh turnaround time, industry fluency, and pricing carefully, since an auditor unfamiliar with GLBA safeguards, FFIEC expectations, or open-banking risk can slow an engagement down significantly and jeopardize a critical deal timeline.
Consequently, this article breaks down what digital banking platforms should look for when evaluating potential partners, so that compliance leaders can confidently choose an auditor equipped to support both their regulatory obligations and their long-term growth.
Top 12 Best SOC 2 Auditors for Digital Banking Platforms
Schellman has grown into one of the most recognized names among SOC 2 auditors for digital banking platforms, largely because it offers a rare “single assessor” model that lets a bank pursue SOC 2 and ISO 27001 concurrently under one accredited firm. Digital banks and neobanks, which often juggle multiple overlapping regulatory expectations, benefit from this coordinated approach because it removes the friction of managing two separate audit teams on two separate timelines. Schellman also invests heavily in emerging risk areas, including AI red teaming and supply chain assessments, which increasingly matter as digital banking platforms integrate machine-learning fraud detection and third-party banking-as-a-service infrastructure into their core stacks.
Features

- AI red teaming and ISO 42001 readiness for banks deploying machine-learning models
- SOC for Supply Chain reporting for platforms relying on banking-as-a-service partners
- Global delivery team supporting multinational digital banking operations
- Structured fieldwork process with clear milestone tracking for audit committees
Pros

KirkpatrickPrice built its reputation on an education-forward audit style, and that approach resonates strongly among SOC 2 auditors for digital banking platforms whose internal teams are still building out formal compliance functions. Rather than simply issuing findings, KirkpatrickPrice’s auditors walk client teams through the reasoning behind each control requirement, which helps banking platforms understand not just what to fix, but why it matters for customer trust and regulatory standing. Every engagement begins with a formal gap analysis that maps existing controls against the SOC 2 Trust Services Criteria, giving digital banks a clear roadmap before fieldwork even starts.
